Definitions

  • This invention relates to dispensing apparatus for dispensing metered quantities of pressurised fluid and in particular but not exclusively to dispensing apparatus for the nasal administration of medicinal products such as insulin.
  • a pressurised dispensing container defining a chamber, a housing for the container defining a bore, the container having a body which is axially slidable in the bore, the container having a metering valve means located at a first end of the body for dispensing metered quantities of fluid and actuated by axial depression of a valve stem defining a dispensing flowpath, a valve actuator fixedly connected to the housing at a corresponding first end thereof and defining a further dispensing flowpath for product fluid dispensed through the stem, and trigger means operable to urge the container body axially towards the first end of the housing such that the valve stem is depressed by relative movement together of the valve means and actuator and thereby dispensing a metered quantity of fluid.
  • a disadvantage of such apparatus is that the product fluid is exposed to a propellant fluid within the chamber.
  • a further disadvantage is that the apparatus must be held in a particular orientation in order for the product fluid to be satisfactorily dispensed.
  • Valve means comprising a collapsible chamber metering valve and the container including means dividing the chamber into a product fluid reservoir communicating with the valve and a propellant fluid reservoir, the dividing means being movable such that propellant pressure is applied to the product fluid without mixing of the respective fluids.
  • An advantage of such an arrangement is that contamination by propellant of the product fluid is avoided. This is particularly important when the product fluid is a medicinal product and especially where the propellant fluid is known to have harmful effects on the person receiving medication or adverse effects on the quality of the product fluid.
  • a further advantage is that the collapsible chamber metering valve enables the metered dose to be substantially unaffected by the attitude at which the apparatus is held in use.
  • the provision of trigger means also has the advantage of enabling the housing and the valve actuator to be held in a substantially fixed position in use and this is particularly convenient where the use requires precise control of the actuator position as in the case of nasal administration of a medicinal product.
  • the dividing means may comprise a free piston axially slidable within the chamber and dividing the chamber into a first portion constituting the product fluid reservoir located forward of the piston and a second portion constituting the propellant fluid reservoir located rearward of the piston.
  • the piston may comprise a forward portion of a first material selected to be substantially chemically non-reactive with the product fluid and a rearward portion of a second material selected to be substantially impermeable to the propellant fluid, the piston portions being composited such that the product and propellant fluids respectively do not contact the second and first materials of the piston respectively.
  • the piston portions may be formed of resilient materials and each portion may include a respective seal formation resiliently biassed into peripheral sealing contact with the inner wall of the container.
  • the respective portions may then each be formed of respective plastics materials and the respective seal formations comprise annular projections formed integrally with the respective portions.
  • first and second materials may be elastomeric, the respective seal formations comprising annular projections of part circular cross-section formed integrally with the respective portions.
  • the piston constituting the dividing means may alternatively comprise a substantially rigid piston body, first seal means peripherally sealing the piston body to the inner wall of the container and formed of a material selected to be substantially chemically non-reactive with the product fluid and second seal means peripherally sealing the piston to the inner wall of the container at a location rearward of the first seal means and formed of a material selected to be substantially impermeable to the propellant fluid.
  • the piston body in this case is formed from an inert and gas impermeable material such as a rigid plastics material or a metallic material for example.
  • the first seal means may be a ring of bromobutyl rubber material and the second seal means may be a ring of nitrile rubber material.
  • Bromobutyl rubber material has been found to be particularly suited where the product fluid contains insulin because this material is less prone to contaminate the product with weak organic acids than in the case of other rubber materials of similar mechanical properties. Such acids are known to render insulin unstable.
  • Nitrile rubber material is particularly suited for use with hydrocarbon propellant fluids where it exhibits exceptionally low gas permeability.
  • the piston body may comprise a forward portion, a rearward portion spaced axially and rearwardly of the forward portion and a connecting portion co-operating with the forward and rearward portions to define first and second annular grooves receiving the first and second seal means respectively.
  • Such an arrangement enables the piston to be conveniently formed from easily mouldable components and facilitates assembly with the seal means.
  • the apparatus may alternatively include a dividing means comprising a flexible bag.
  • the interior of the bag may define the product reservoir with the mouth of the bag comprising an annular flange secured in sealing contact with a co-operating flange of the valve.
  • the container may then be secured to the valve by means of a crimped valve ferrule such that the flange comprising the bag mouth is clamped between an annular lip of the container mouth and the valve flange.
  • the space between the external surface of the bag and the container wall thereby defines the propellant reservoir in such an arrangement.
  • the propellant may be contained within the flexible bag with the product reservoir external to the bag.
  • the valve would communicate with the chamber so as to communicate with the product reservoir.
  • the actuator may comprise inner and outer nested components, the actuator including a break-up nozzle for atomising dispensed fluid, which nozzle includes swirl inducing ducts defined by groove formations formed in one or other abutting surfaces of the inner and outer nested components respectively.
  • An advantage of such an actuator is that the need for a nozzle disk is obviated and avoids the danger that such a disc might otherwise be displaced during a dispensing operation. This is particularly important where a medicinal product is dispensed for inhalation nasally or orally in which case a displaced nozzle disk would present a serious hazard.
  • the inner nested component includes a first tubular portion fitting onto a stem of a co-operating dispensing valve, the outer nested component including a second tubular portion fitting onto the first tubular portion and the first tubular portion being provided with an axially extending groove defining an axially extending dispensing flowpath.
  • the trigger means may comprise a trigger member which is pivotally mounted with respect to the housing and further comprising means transmitting pivotal movement of the trigger member to axial movement of the container.
  • the trigger member may be slidable with respect to the housing and may further comprise means transmitting sliding movement of the trigger member to axial movement of the container.
  • a trigger member may include at least one projection extending through an aperture of the housing and engaging a co-operating formation of the container, the trigger member being axially slidable and the container being slidable in unison therewith with respect to the housing.
  • the trigger means includes audible indicator means such that an audible indication is generated upon each actuation of the trigger means.
  • the dispensing apparatus includes viewing means for viewing the quantity of fluid remaining in the container.
  • the viewing means in a preferred embodiment comprises a transparent window formed in the housing.
  • the apparatus further includes locking means for selectively locking the trigger means against accidental actuation when not in use.
  • the apparatus further includes a detachable cap for the first end of the housing, which cap includes a pocket clip means.
  • the dispensing apparatus when so assembled with a cap may then have the external appearance of a conventional fountain pen and may be carried in the pocket of the user in like manner.
  • the apparatus 1 of Figure 1 comprises a cylindrical housing 2 defining a bore within which a cylindrical pressurised dispensing container 3 is located such that a body 50 of the container is coaxially slidable.
  • the container 3 defines a cylindrical chamber 4 within which a free piston 5 is coaxially slidable.
  • a first end 6 of the container 3 is located at a first end 7 of the housing and includes a collapsible chamber metering valve 8 of the type which is actuated by depression of a valve stem 9 relative to the valve body.
  • the construction of the valve 8 is such that the stem 9 is spring biassed into a normally extended position in which the valve is in a closed (non- dispensing) condition.
  • a dispensing channel 10 extends axially through the valve stem 9 and defines a dispensing flowpath.
  • An actuator 11 is connected to the housing 2 at the first end 7 and receives the valve stem 9 in an axial bore 12.
  • the actuator 11 is of two part construction comprising an inner component 13 and an outer component 14, the components being nested together.
  • the inner nested component 13 is cylindrical and extends coaxially with the housing and includes an axially extending groove 15 which is overlaid by the outer nested component 14 to define a flowpath for dispensed fluid, the flowpath communicating between a nozzle 16 formed in the outer nested component and a radial port 17 communicating with the bore 12.
  • Swirl inducing ducts 18 are provided by surface formations in mating surfaces of the inner component 13 and the outer component 14 adjacent to the nozzle 16.
  • the fluid flowpath provided by the actuator 11 therefore extends from the stem channel 10 into the bore 12, through the port 17 into the groove 15, through the swirl inducing ducts 18 and out through the nozzle 16.
  • the swirl inducing ducts 18 are shown only as a thickening of the line defining the upper-most end of the inner nested component 13.
  • the ducts are arranged to conduct fluid in a generally radially inwardly direction whilst inducing swirl movement in the conducted fluid, the shape of the ducts corresponding to the ducts provided in known break-up nozzle disks
  • the outer nested component 14 includes an annular outer rib 19 which is a snap fit within the first end 7 of the housing 2 thereby forming an end closure to the housing.
  • the cap 20 is a push fit onto the actuator 11 and provides a protective enclosure when the apparatus 1 is not in use.
  • the cap 20 includes a pocket clip 21 similar to that provided on conventional fountain pens.
  • the container 3 has a body of a transparent plastics material which is closed at its first end 6 by the valve 8 and at its second end 22 by an end wall 23.
  • An elastomeric plug 24 is provided in the end wall 23 to allow filling of the container with propellant.
  • the piston 5 within the container 3 divides the chamber 4 into a product fluid reservoir 25 forward of the piston i.e. adjacent to the first end 6 and a propellant reservoir 26 rearward of the piston i.e. adjacent to the second end 22.
  • the piston 5 is of composite construction and formed from a forward portion 27 of butyl rubber material which is disposed facing the product fluid reservoir 25.
  • a rearward portion 28 of the piston 5 is formed of nitrile rubber material and is disposed facing the propellant fluid reservoir 26.
  • Each of the piston portions 27 and 28 is formed having a cylindrical cup shape and the portions are connected in back-to-back fashion such that the composite piston 5 is of H-section.
  • Portion 27 and rearward portion 28 are bonded together during the moulding operation by which the piston is formed.
  • the piston 5 is freely slidable in the axial direction along the container 3 whilst forming a sufficiently tight seal against the container walls to prevent mixing of the propellant fluid and product fluid.
  • the composite construction of the piston 5 ensures that the propellant fluid comes into contact only with nitrile material of the piston and that the product fluid comes into contact only with the butyl material of the piston.
  • the trigger means 30 comprises a trigger member 31 which is pivotally mounted about a pivot 32 which is located adjacent to a sidewall portion 33 of the housing with a pivotal axis being defined tangentially with respect to the sidewall portion.
  • the trigger member 31 includes a cam 34 having a cam surface 35 arranged in contact with the end wall 23 of the container 3.
  • the trigger member 31 further includes a lever arm 36 which extends generally axially with respect to the housing 2 and includes a finger grip surface 37.
  • the trigger member 31 is configured such that upon depression of the lever arm 36 the trigger member rotates about the pivot 32 such that the cam 34 bears upon the end wall 23 in order to urge the container axially along the housing 2 in a direction away from the trigger means.
  • the trigger means 31 further comprises an audible indicator means 38 comprising a resilient detent 39 extending generally radially with respect to the pivot 32 and co-operating with a fixed detent 40 extending generally inwardly of the housing 2 such that during depression of the trigger lever arm 36 the respective detents 39 and 40 are snap engageable to produce an audible click.

  • a locking clip 41 is provided for locking the trigger means in an inoperative condition as shown in Figures 1 and 2.
  • the locking clip 41 is part cylindrical having an outer portion 42 which overlays one side of the second end 29 of the housing 2 so as to cover the lever arm 36 and includes an inner portion 43 in the form of an insert within the open second end 29 of the housing and which is configured so as to positively restrain the lever arm 36 from accidental rotation.
  • the inner portion 43 and the lever arm 36 are snap engageable such that the locking clip 41 may be removed by moving axially away from the housing 2 before use of the apparatus 1.
  • the locking clip 41 includes an axially extending slot 44 through which the lever arm 36 is visible.
  • the housing 2 includes a window 45 through which the product fluid reservoir 25 may be inspected in order to determine the quantity of product fluid remaining.
  • the cap 20 together with the locking clip 41 are removed from the housing 2.
  • the apparatus 1 is then postioned with the nozzle 16 directed towards the location to which product is to be dispensed and the trigger means 30 is actuated by depression of the lever arm 36.
